50 µg/ml

How do you calculate antibiotic concentration?

Make sure units match!

1. C1V1 = C2V.
2. C = concentration; V = volume.
3. Example: You have a stock solution of A at 100mg/ml. You want 150 ml at 100ug/ml.
4. (100ug/ml)(150ml) = (100000ug/ml)(x)
5. 15000 = 100000x.
6. x = 0.15ml, or 150ul.
7. Remember that you have to convert mg/ml to ug/ml, which you can do by multiplying by 1000.

How do you make 100 ug ml ampicillin?

Why carbenicillin Cannot be given orally because?

Carbenicillin and indanyl carbenicillin (Fig. 20-7), its α-carboxy ester for oral administration, are no longer used because of the large doses required, the greater potential for toxicity, and the availability of more potent alternatives.

Is carbenicillin a carbapenem?

Their unique molecular structure is due to the presence of a carbapenem together with the beta-lactam ring. This combination confers exceptional stability against most beta-lactamases (enzymes that inactivate beta-lactams) including ampicillin and carbenicillin (AmpC) and the extended spectrum beta-lactamases (ESBLs).
